Have a six month old miniature schnauzer. We have had a few more friends round this week because its been half term and our puppy is not very friendly to visitors has been barking at them sometimes it seems aggressive. Think she is a highly strung dog, she goes potty in the street on poor unsuspecting people ,she is better with other dogs and owners once she has had a sniff 
Am just worried I will have no friends left! Anyone else any advice do you think she will get better as she matures. She loves my mum and when she visits goes potty in a good way like she does us.
